Lenny I had my daughter help me do some further research on this site http://www.superior-industries.com/ultra_glide_product_213.html?gclid=CJCi06a5-4
two cans for $60 is way out of my price range at the moment better deals if you buy the cans by the dozen but I'd have no use for that much spray. However we descided today to try some other suggestions and I will put a piece of 3 by 5 recipe card by each window , using different things and lets see which one still works best say in 6 or 12 months. . thanks for all the great responses.
